Which of the following correctly states the functions of the rough endoplasmic reticulum? a. lipid metabolism, cholesterol synth
esis, and synthesis of the lipid components of lipoproteins b. synthesis of cellular membrane components c. absorption, synthesis, and transport of fats d. storage of calcium ions
Endoplasmic reticulum is a network of membranes fistulas; within the cytoplasm of a eukaryotic cells, where proteins and lipids are synthesized usually connected in continuum with the nuclear membrane of the cell.
The ER is of two kinds the smooth and the rough ER (Endoplasmic reticulum).
Functions of Rough endoplasmic reticulum includes; * Synthesis of protein * Degradation of worn out organelles
While the functions of Smooth endoplasmic reticulum includes; * Synthesis of lipid and steroids * Role cellular metabolism * Storage and metabolism of calcium * Catabolism of toxic substance.
Inference from the functions stated above shows that ER is actively involved in the synthesis of cellular membrane components.
The Rough ER so called because of the presence of ribosomes attached to its walls.is an organelle with mutifunctions, Athough it is known for modification and transport of protein synthesize by the ribosomes: It function in production of cell membrane components
1.Involved the formation of integral proteins in the cell membrane; which facilitated movement of ions and large polar substances across the cell membrane. integral proteins are most alpha proteins with uncharged polarity to interact with the hydrophobic phospholipid bilayer,
and
2. It serves as production site for lipid needed in other cell membranes.
Matter is mass, Element is matter, and Atom is element.
Explanation:
Matter is anything that has mass or takes up space (Volume). Matter is made of elements. Elements such as carbon dioxide or gold. An atom is the smallest unit of matter. Elements are made of atoms. Atoms are what chemically makes an element. :) Hope she gets her phone!
